The result from BLAST homology of bacterial strain IB.6a.1 showed that this bacterium is affiliated to the genus
Bacillus. The isolate IB.6a.1 come from Sargassum polycystum. The phylogenetic tree showed that isolate IB.6a.1 is
most closely related with Bacillus subtilis with 95 % sequence similraties (Fig. 2). The partial 16S rRNA sequence
of this strain active associated bacteria was deposited in DDBJ (DNA Data Bank of Japan) with accession number
